WATER-GAGE erases.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed December 2. 1907- Serial No. 40 L701.

all i/Jiiom it may concern:

it known that l, dons OCoNNoR, citiizen of the United States, residing at Clifton, Staten island, in. the county of Richmond and State of -blew York, have invented new and useful Improvements in ater-Gages, oi. which the billowing is a specification.

My invention pertains to water gages for use in connection with steam boilers and other' water holders; and it consists in the s1 durable and eincient water gage hereinai tor described and claimed.

in e drawings accompanying and forming pint this specification: Figure 1 1s a view, partly in elevation and partly in vertical. s ction, of the water gage constituting be ctical embodiment of my invenich ll am aware. Fig. 2 is an elethe intermediate member comprised in the irame of the gage, and: Fig. 3 is it her cl l section taken 1n. the plane inline of Fig. looking of reference designate cor- .s in all of the views of the water comprises a tube A, of or other transparent material suitable to the purp aframe, preferably of metal, containin and holding the trans and gaskets B, preferably of rubber, surrounding and snugly receiving the end portions oi the transparent tube and having for their oiiices to prevent the leakage of water from the frame.

".lhe tube-h lding frame is made up of an intermediate member 0 and end members D, and, termediate member-is provided with a longi tudinal, bore c oi a diameter to snugly' rethe tube A, interior shoulders i) at the ends of e said bore a, and intcriorly threaded, enlarged end portirms c which are, by prcierence, eirteriorly of angular form as shown. Said intermediate member'C is also provided with upright, diametrically opposite sight openings at which extend from a point adjacent to its lower enlargement c to a point adjacent to the upper corresponding enlargement c and are tapered or gradually increar-ierl in width outward. By reason of the said sight openings nbeing arranged diametrically opposite each other, it will be ob vod that the height of the t ater in the tube it may be on by persons standlng'at opposite sides of the gage; and it wlllalso best shown in Figs. 2 and 3, the in-" of the sight openings a person does not have to stand in line with the tube but may stand at o posite sides of said line and yet distinct y see the tube and the water therein.

The end members D of the frame for re ceiving and holding the tube A. are identical in construction, and for this reason a detailed description of the end member D shown at the bottom of Fig. 1 will suffice to impart a definite understanding of both. The said end member D, Fig. 1, 1s provided with a bore m in line with that of the tube A, and an enlargement m at the inner end of bore m, and is also provided with a shoulder p arranged to abut against the end of the interme iate member C, and is further pro-- vidcd with a reduced and exteriorly threaded portion r which is turned into the threaded enlargement c of the intermediate member C and against the lower washer B so as to crowd the said washer against the interior shoulder b of member O and thereby assure the washer or gasket snugly surrounding the end portion of the transparent tube with a view of precluding leakage of water from the meeting portions of the intermediate and end frame members. My novel gage is designed more particularly for use on steam locomotives; and it will be gathered from the foregoing description that the said gage as a whole is well adapted to withstand the excessive vibra" tion to which the ages on locomotives are ordinarily subjects It will also be gathered that the gage is compact and durable, and

that in addition to the practical advantages hereinbel ore ascribed to the tapered si ht openings (1 in the intermediate frame mom or O, thesaidsi ht openings permit of the transparent tn )9. A being readily seen, and yet expose but a small portion of the area of the tube with the result that the liability of the tube being. struck and broken is reduced to a minimum.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

In a water age, the combination of a transparent tu e, an intermediate frame member having a longitudinal bore, of less length than the tube, snugly receiving said tube and also havinginteriorly threaded, end enlargements, interlJr shoulders at the ends of said bore and upright,. diametricallyopposite sight openings tapered or gradually reduced in width from the inside of the member to the outside thereof, end frame members each havin a bore in line with the transparent tube an an enlargement at the inner end of said bore snugly receiving an portions of the transparent tube and inter- 20 I posed between the interior shoulders of the intermediate member and the inner ends of the end members.

In testimony whereof I have hereunto set my hand in presence of tWo subscribing Wit- 25 DGSSGS.
